Default TIP: 1/4 inch socket with isolated switch/es

On 2/15/2010 12:30 AM N_Cook spake thus:

I'm getting rather tired of seeing band amp failures due to the use of these
flimsey domestic grade of amp headphone sockets. Even if you can get hold of
one off replacements, rather than minimum of 100 , what is the point of like
for like replacement if only 3 years of use, not abuse, leads to amp
failure.

Current one carried a negative rail for switching purposes so definitely
isolated switch action required.
Starting with a standard 2 way or 3 way chassis or pcb mount socket. For 1 2
or 3 isolated sockets and continued use of the 3 tip/ring/ground contacts to
an inserted jack.
Rough up mechanically the outer surface of the moving contact. Solder,
deliberately messily for later glue bonding, some highly flexible hookup
wire to the end of a moving contact at the switch contact end.


[snip remainder of bodgery]

Honestly, Norm, you and Patrick Turner, the guy who likes to mutilate
Conrad Johnson amplifiers and such (over in rec.audio.tech) ought to get
a room together.
